A saddle ride type all-terrain vehicle includes left and right front wheels supported independently of each other on a vehicle body such that driving power is transmitted to said front wheels by way of a pair of left and right drive shafts extending from a driving source side. The vehicle also includes universal couplings provided at opposite end portions of each of the drive shafts, covered by rubber boots. The vehicle further includes a protector for covering the rubber boots.

The invention discloses an engine with compression ratios variable. The engine with the compression ratios changeable comprises a cylinder body, a cylinder cover, a cylinder cover cap, a cylinder barrel, a bent axle, a connection rod and a piston, and is characterized in that a groove is arranged at the center of the top end of the cylinder cover, and a wheel is arranged inside the groove. A cam is arranged on the upper portion of the wheel and is fixedly connected on a cam shaft, wherein one end of the cam shaft is provided with a cam shaft gear, the cam shaft gear is driven by a bent axle gear at one end of the bent axle through a transmission mechanism, and the transmission mechanism can ensure changes of relative angles between the cam and the bent wheel. The periphery of the upper edge of the cylinder cover is connected with the periphery of the lower edge of the cylinder cover cap through an upper rubber boot, and the periphery of the lower edge of the cylinder cover is connected with the periphery of the upper edge of the cylinder body through a lower rubber boot. Two pins are symmetrically arranged on the left lower side and the right lower side of the cylinder cover. Sleeves are arranged on the left upper side and the right upper side of the cylinder body and match with the pins in a sliding mode. Springs are sleeved outside the pins and the sleeves. The engine with the compression ratios variable can change the compression ratios of the engine, effectively improve power of the engine and improve fuel oil economical efficiency.

Provided is a suspension type anti-vibration member, capable of meeting the demand for small-sized and light anti-vibration member and ensuring the anti-vibration effect by preventing the contact between the anti-vibration material and the anti-vibration member body even if the position of the inserts and the position for setting vibration device stagger with each other. The suspension type anti-vibration member comprises: an anti-vibration body (suspension member box) which, arranged at the midway (between the upper hanging bolt and the lower hanging bolt) of the suspending bolt of a vibration device for producing vibration during suspension, bears the load of the above mentioned vibration device, an anti-vibration material (tapered spiral spring or tapered rubber spring) which, arranged between the upper edge and the lower edge of the anti-vibration member body, is used for absorbing the vibration of the vibration device, and two elastic members (rubber cap and rubber boot) arranged between the anti-vibration material and the anti-vibration member body as well as between the anti-vibration material and the suspension bolt. The suspension type anti-vibration member prevents the vibration spreading of the vibration device, with the anti-vibration material in a shape of tapered table.
